Daniel Merlin Lund, from the United States, has been engaged in photography for 36 years and published e-book in Amazon. On our way back to Chongli from the prairie road, we met a couple of old men with weather-beaten faces. The old woman was selling some wreaths, and the old man was leaning against the lamppost to make them. When he asked, he learned that the old woman was eighty years old, and that the old man was eighty-one. The two old people did not stay at home, but also came out to insist on labor. They wove garland materials of wild pepper flowers on the mountain. Grandma said with a smile, “Dried flowers can be used to stew mutton. Delicious.” Daniel Merlin Lund came forward to talk. Grandpa learned that he had lived in Africa for many years, actually hand in the hands of the knitting wreath to Daniel Merlin Lund. He said, “You Africa is too poor. This wreath is free for you.” What simple people! What a lovely old man! Zhang Tianhong was happy to take a photo with them.“The food here in Zhangjiakou is so delicious. The people here are so nice. These are the most unforgettable time of my life.”
